Peer-to-peer (P2P) is a type of computer network architecture that allows users to share resources and exchange data directly with each other, without the need for a central authority or server.
In a P2P network, every user acts as a client and a server, enabling a decentralized distribution of data and resources. This allows for greater resilience, security, and scalability than traditional client-server networks.
P2P networks are used for a variety of purposes, including file sharing, voice-over IP (VoIP) communication, online gaming, and cryptocurrency transactions. Some of the most popular P2P networks include BitTorrent, Skype, and the former Napster.
One of the critical advantages of P2P networks is that they are decentralized, meaning that they are not subject to a single point of failure or control. This makes them more robust and resilient, as users can continue to communicate and exchange data even if one or more nodes fail.
